与对比度增强的MRI (CE-MRI) 在缺血性心脏病患者中检测到左心室 (LV) 血栓,比胸回声心脏成像 (TTE) 更好. 通过CE-MRI检测出更多的血栓,特别是在具有较大的LV体积和较低射出分数的血栓中.
科学领域:
- 心血管成像 - 心血管成像
- 医学诊断 医学诊断 医学诊断
背景情况:
- 心室血栓形成是缺血性心脏病的常见并发症.
- 胸前回声心电图 (TTE) 是标准的诊断工具,但其有效性有限.
研究的目的:
- 评估对比增强磁共振成像 (CE-MRI) 在检测心室血栓中的作用.
- 为了比较CE-MRI与TTE的诊断性能.
主要方法:
- 57名患有缺血性心脏病的患者接受了CINE-MRI和CE-MRI.
- 研究分析了心室血栓瘤,心肌亡,痕和无反流区域.
- 将CE-MRI发现与CINE-MRI和TTE结果进行比较.
主要成果:
- CE-MRI描绘了12幅壁画 (平均尺寸为3.1厘米),通常在LV顶部或anteroseptum.
- 血栓形成与较大的LV终端-透析体积,较低的射出分数和心肌损伤相关.
- 在TTE检测中,只发现了5个血栓,其中3个疑似的上角血栓在MRI上是正常的.
结论:
- 在患有缺血性心脏病的患者中,CE-MRI在识别左心室血栓方面优于TTE.
- 此外,CE-MRI还有效可视化心肌缩和痕组织.
